Sorry, I am totally new to Android as I am an iPhone user. I am interested in a dual sim chinese android phone (Lenovo A750 looks pretty interesting) as I live between Britain and Italy, which makes it more convenient to use a single phone rather than two different ones.
However, don't know about operating system/firmware updates. With an iPhone, everything runs smoothly through iTunes, but what about updating a modified chinese Android phone ? Are firmware and operating system updates different ? Thanks !
